One of my favourite heroine team-ups from the Silver-age/Bronze-age comics.

From Batman Family #17: 15 out of 62 pages.

Both Poison Ivy and Catwoman are planning individual heists and turn to then newcomer Madame Zodiac for "future broadcasts" of their success.

Of course, it's only to be expected they'd both call rubbish on their foretold encounters, but Madame Zodiac maintains she is 110% accurate. Either way, Both Cat and Ivy go their separate ways to carry on with their agendas. Ivy is of course taken out by Babs, but Babs is effectively also taken out by none other than Madame Zodiac, but only for the sake of teaching Ivy a lesson about doubting her.

Then, Enter Catwoman and Huntress, who--unbeknownst to Cat--is her own daughter from a parallel universe.

And of course, Huntress is also shortly knocked out by Madame Zodiac as another lesson to Catwoman about having her doubts. (Oh Huntress...I love you and all...but you need better lines my dear...)

Now that all lessons have been learned, Madame Zodiac proposes a heist of her own, but needs the cooperation of both Cat and Ivy. (The only time in history that a team-up between Catwoman and Poison Ivy actually ever made sense...)

Unbeknownst to Pammy and Selina though, Babs, Helena, and Kathy Kane have also planned a trip to the museum for no other reason than to stop a heist. Go figure!

(Huntress wouldn't let the Cat have her yarn for one minute, so of course she's going to take it out on that crossbow!)

Poor Ivy and Cat. They both got ditched by Madame Zodiac who made off with the merchandise. Bastard!

And because we've only seen what Helena Wayne has learned from her daddy, time to see what skills she did learn from her mommy!

Bypassing maximum security, lock-picking, and kicking around males who get in the way? Definitely Catwoman traits! She did in fact acquire the best skills from both her parents. (Still need better dialogue here Huntress...)

Nevertheless, despite writers not being able to break any cliches with Helena Wayne, something good still came out of Helena beating the Earth-1 version of her mother after all. Years later, Selina actually decides to go straight for Batman.

Batman is so impressed with her new attitude, he actually allows her to take him out on a date. Dawwwwww!

A bloody shame the world(s) ended before we had a chance to see where this would have gone. I guess we'll never know of Helena Wayne would have been born on Earth-1 too. :/
